Burrowing Centipede

Morph {2}

When this card is flipped face-up, target another creature, then activate the corresponding effect.

If the targeted creature is face-down, flip it face-up, ignoring any cost.

If the targeted creature is face-up, flip it face-down as a 2/2 colorless creature. Its controller can flip it face-up any time for its mana cost, unless the creature has morph, then they can pay the morph cost instead.
